I think that Grigori Adventurers should not count toward the National Unit limits. I don't, however, know if this is possible. If it isn't, how about allowing Grigori to have 5 of each national unit instead of 4? I think that would be in keeping with their individualistic approach to things, and would amp up their power a bit.
As it stands, the Adventurers are nice (especially in the early/mid game), but since they take up Tier 4 slots, they aren't really equal to the raw extra firepower of normal heroes. The Hippus hero, for example, is basically a fifth knight. But Adventurers basically take up slots that normal units would otherwise get, and prevent the normal army from getting all that strong.
Grigori seem to be regarded as kind of a middling power... cool and flavourful, but their special mechanic not really making up for the massive penalty of no religion. So I think this bonus would balance it out. Just from 4 to 5, though... wouldn't want to make them too strong.
